I’m beginning prep for a large project that’s going to be installed 2 miles from the ocean in San Diego, CA that include a number of building facades as well as 3d characters. We’re on the hunt for a long-lasting exterior sealer that’s going to help prevent UV and salt damage. Most of our substrates are either di-bond, fiberglass, steel, or MDO and the plan is to paint them with a multi-surface acrylic. The park is asking for a 5 year warrantee, so I’m looking for a sealer that’s going to really be protective with kids, water, and sun, all over the scenery 10 months out of the year. Unfortunately, we don’t have the set up to accommodate using an automotive clear coat, so that’s out of the running. Below are some of the options we’ve either had experience with or are considering:
I’ve just started researching into UV-cured sealers (like how gel nail polish works), but haven’t gotten to far so I’m not certain if it would be feasible on such a large scale. Anyone have relevant experience with the above products or suggestions for other sealers or avenues to explore?
